Add a bit more RAM and locate it where-ever there are unused addresses in the address space. Let's see what the maximum amount of RAM can be for an otherwise stock A500. :-D
Naturally we'd have to add the weirdly located bits of RAM with addmem commands, but who cares. :-)
If you don't think this is a good/fun idea, I'll be serious and ask you to please at least add maximum $c00000 RAM for a little compatibility boost. Exec will auto-add that if found. That'd make my A500+ very happy.. 2MB chip, 8MB z2 fast and 1,7(?)MB of c0 fast.
